> Maybe there isn’t an order and the user has to be aware that the chemical has multiple, simultaneous hazards

 

There are various categories with a specific hazard class (for example, 1-4 for flammable liquids), but it doesn't seem reasonable that they were intended to compare the degree of hazard associated with a specific pictogram, since the units of the associated hazards are entirely different. So, I don't think the fact that a chemical is a Class 3 flammable is more or less important than it being a Class 2 carcinogen. It depends on the scenario you're evaluating as well as the chemical…
